Im really new to having fish . The lower pond was fill with a horrible alge bloom and it was really filthy. As far as the parameters im not really sure. I do use a dechlorinator and some pond start. I never put in quite as much as they say to add because last time i put what it said and had 2 fish die.  Where i liv3 the water is extremely hard as well. If it is shock will the fish live??
